How to restrict things your kids can do within apps with Guided Access

With a super useful feature called Guided Access, an iPhone, iPad or iPod touch can be put into so-called kiosk mode that temporarily restricts the device to a single app. It's the ultimate iPhone and iPad lockdown feature, and it's already built-in.
This tutorial discusses using Guided Access to control which app features are available to your children, what they can touch and interact with inside an app.
We'll also detail other Guided Access capabilities allowing parents to shut down sensors, turn the hardware buttons off, disable areas of the screen where an accidental gesture might cause a distraction and more.
